Instrumented Mouthguard to Determine Accurate Head Motion During Impacts
Stanford researchers at the Camarillo Lab have designed an instrumented mouthguard which provides accurate measurements of head motion during impacts. The accurate measurements are achieved by rigidly affixing sensors to dentition in the mouth, which are a part of the skull, and are designed to isolate the measurement sensors from perturbances caused by the jaw closing.
Studies using the working prototype showed that this new method can better distinguish between truly dangerous head blows and noise, compared to existing technology.
